HENRY G. LILIENTI-IAL, OF SAN FRANCISCO, CALIFORNIA.

DRINK-MIXING MACHINE.

Specification of Letters Patent.

Application filed September 23, 1910. Serial No. 583,529.

To all whom it may concern:

Be it known that I, HENRY G. LILIEN- TI-IAL, a citizen of the United States, and a resident of San Francisco, in the county of San Francisco and State of California, have invented a new and useful Drink-Mixing Machine, of which the following is a specification.

My invention relates to that class of rnachines which are employed for temporarily holding and violently shaking a receptacle or receptacles in order to thoroughly mingle (and generally to cool) the ingredients of various beverages. Various devices of this class are in general use, with varying degrees of success, but all such as have come under my observation have some one or more objectionable features.

The principal object of my invention is, therefore, to generally improve the efficiency, construction and capacity of such machines whereby better results will be produced. In the evolution of this main object several subsidiary ones have been developed, among them being to improve the shaker-frame or holder, whereby each individual shaker and the glass with which it co-acts is independently held, thereby eliminating the heretofore objectionable feature of binding and cramping the frame aforesaid, especially when a single drink was be ing mixed. In this connection it will be manifest, as this feature of the invention is further disclosed, that when all the shakers are being simultaneously used, and the glasses chance to be of uneven sizes, unless independence of movement of the individual shakers is obtainable, the liquids will be violently forced out from between the shakers and the glasses and promiscuously distributed in an extremely objectionable manner.

Devices of this character as heretofore constructed have been productive of violent jarring and j olting and of excessive noises to such extent, in fact, as to render them unsalable in many places.

It is another object of the invention to improve the direct vertical reciprocating movement of the shaker-holder, and this object I accomplish mainly by the use of a crosshead acting in a guide or trunk within the pedestal. In this connection the invention further contemplates the use of a counterweight pulley-wheel to supplant the prior devices for reducing vibration.

It is also an object to provide improved means for raising the holder to admit the shakers and glasses.

Other objects will be in part obvious and in part pointed out.

In the accompanying drawings all my improvements are shown as embodied in the best way now known to me; obviously, however, some of these improvements may be used without the others and in machines difiering in construction and organization from the one shown.

In said drawings:Figure 1 is a front view, partly in elevation and partly in section. In this figure some of the springs are omitted from the sectional portion-their locations will be understood from that portion of the figure which is in elevation, inasmuch as they are duplicates. Fig. 2 is a vertical, central, transverse section; Fig. 3, a detail perspective; Fig. 4, a detail an elevation of the counterweight wheel, seen from its inner end; and Fig. 5, a plan view of the crosshead.

Like parts are denoted by corresponding numerals of reference throughout the several figures.

2 indicates the main casting or pedestal, provided at each side with a vertically disposed bearing 3. The pedestal is hollow and its upper interior portion is cylindrical as shown best in Fig. 2 to form a trunk or guide 4 for the crosshead presently described. It is provided at its front portion with a horizontal bearing 5 for the footlever rock-shaft 16 and at both its front and rear portions is provided with hand holes which are normally covered by plates 6 and 7 respectively, the latter projected outwardly to form a bearing 8 for a shaft 9 the inner end of which is integral with or fixed to a crank-disk 10 having a wrist-pin 11 to which the connecting rod 12 is attached in the ordinary manner, and on the outer side of which shaft is a counterweight pulleywheel 13 fixed by a key 14:.

15 is a grease-cup.

As has already been stated, the foot-lever rock-shaft 16 is mounted in the bearing 5. The foot-lever 17 is suitably fixed on this shaft, preferably by a spline (not shown) and at its free end is provided with a footpedal 18 pivoted thereto. Fixed on the rock-shaft at each side of the foot-lever is a pair of cams, 19, 20. These cams project through slots 21 in the bearings 3, and their extremities project preferably into, and. in

thec'ourse of their movement quite through similar slots in the rear portions of said bearings. .Recrprocally mounted 1n the vertical openings in sald bearings are cylindrical' blocks 22 each provided with a slot 23 in its lower portion. The cam-ends rest also inthese slots and thereby not only preadjusted bylock-nuts 25, are elevated to therebyiraise feet 26 which will presently be described, Surmounting the pedestal 2 is a cap 27 the tubularstem 28 of which seats in the like top of thepedestaland is restrained by a flange 29 and locked by a screw 30. The up; per portion '40 of the cap is cylindrical to provide a guide for the shaker rod hereinafter described. Each of its lateral arms 31 is apertured to form eyes for the reception of one of the stems 24 for which it forms a guide. Each stem 24 is fitted with a collar '82, and thatvportion of each stem which is V p which is of the trunk-piston type and which is adapted for reciprocation within the disposed between said collar and the eyes above recited is embraced by a contractile spring 33, while the upper end offeach stem supports one of the feet 26 hereinbefore referred to and which feet are adapted to-elevate the shaker-frame rods presently described.

The upper end of the connecting rod 12 is pivotally engaged with the crosshead 34 trunk 4 which forms a guide therefor and whereby a true, .steady and free motionis derived and jarring and jolting eliminated;

The lower portion of the shaker-rod 35 is threaded into the upper portion of the crosshead and derives motion therefrom in an obvious manner.

; On a bracket 36 suitably fixed on the rear face of the pedestal is bolted a motor 37, the

shaft 41 of which extends inwardly and car- 'ries a} sheave 3 8, which sheave and the conn- 7 .terweight pulley are embraced by a belt 39.

One of the chief difliculties heretofore met with in this classof devices has been that the shaker-frameor clamping-frame would bind, cramp and. becomedistorted, especially whenbut a singledrink was being mixed.

This has arisen because. no provision has been made whereby the individual shakerholders could act independently of each other. In my improved construction, shown best at Fig. 1, 42 is a shaker-platform providedl with a centrally disposed aperture into which is threaded the upper end of the shaker-rod 35, rigid securement being efgfected by a lock-nut 43. The ends of the platform are turned upwardly at right angles to the base, and each end is apertured to provide an eye for the reception and passage of a clamp-rod 44. It is further apertured for the reception of an inner pair of rods 45 and for intermediate rods 46, all of which rods have movementin said apertures. Each of'said rods is provided with a nut 47 resting above the platform, and the lower end of eachrod is lifted with a nut 48. An expansion spring 49 embraces that portion of each rod which lies between the platform and the nuts 48. The platform is suitably recessed at '50 for the reception of the bottoms of metallic shakers, not shown. Each pair (three) of'clamp-rods is fixed at its upper portion in a clamp-plate 51, the central portion of eachof which supports a semi- ;spherical cushion 52 of rubber, cork or other analogous resilient material or substance. Fixed on the inner pair of rods (45) are bracket-arms 53, the outstanding portions of which are provided with eyes through which the intermediate rods 46 freely pass, these brackets uniting the upper portion ofthe shaker-frame and preventing it from spreading, while permitting each of the component and individual parts thereof to act independently of the others when vibration takes place or when it is desiredto position or remove a glass and shaker. It will be manifest that a'single glass and shaker maybe positioned withoutthe employment of the foot lever, or manually. I

NVhile the shaker-platform consists of a single piece and is a foundation for the entire shaker, the fact that each plate 51 is vibratile by its own pair of rods renders each of such plates and pairs of rods an independently vibratilefshaker, and I desire that said term, wherever herein used, shall be so construed.

Theoperation: Let it be supposed that the parts are occupying the relative positions shown in Fig. 1. To insert a glass and the metallic shaker with which it co-acts, the operator will place the latter in an upright position (and containing the beverage) in any preferred one of the recesses 50. Then depressing the pedal 18 he will, through the instrumentality of thelever l7 actuate the cams 19 and 20 to force the blocks 22 and thereby the stems 24 andfeet 26 upwardly until the latter strike the nuts on the lower ends of the clamp-rods, thus compressing the springs 49 and elevating the clamp-plates '51, whereupon the concaved bottom of an inverted glass may be placed over the cushion. Upon the foot-lever being released, the

springs 33 and'49 which were compressed by the movement just described will expand and return the foregoing parts to their normal positions, the mouth of the glass being simultaneously brought down into the larger mouth of the thin and somewhat resilient metallic shaker to form a water-tight union or seal. Upon the motor being started it will, through the means of the interposed sheave, belt, and counterweight pulley, impart a predetermined speed (or rapidity of revolutions) to the crank-disk 10, which will transmit motion to the connecting rod and thereby impart reciprocating movements to the crosshead which will impart like movements to the shaker-rod and frame, whereby the beverage or beverages will be rapidly shaken from the shaker to the glass and vice versa in an evident manner. stoppage of the motor and pressure on the foot-pedal will bring the parts into position for removal of the glass and shaker.

The counterweight steadies the machine to a degree hitherto unapproached. Lubricant may be applied to the crosshead by means of the oil-cup 60 to cause it to run in the trunk 4: so smoothly and with so little unsteadiness that the jarring and jolt-ing incident to other machines is eliminated. The slotted blocks work with perfect freedom in their bearings and hold the stems in perfect alinement with the eyes through which they pass. The bearing 40 causes the rod 35 to run absolutely true and without racking or noise. There can be no binding of the individual shaker-holders nor of the shakenframe as a composite body, because of the fact that each holder is independent of its fellows.

I am aware of Patents Nos. 457,938 and 473,643, granted to R. D. Schroeder August 18, 1891. and April 26, 1892, respectively, and hereby disclaim specifically any of the devices and combinations therein shown and described.
